Failure to Update the Schema

ScyllaDB relies on the Raft consensus algorithm, which requires at least a quorum of nodes in a cluster to be available. If some nodes are down and the quorum is lost, schema updates fail.

See :doc:Handling Node Failures <handling-node-failures> for information about recovery actions depending on the number of nodes and DCs in your cluster.
